Goldman Sachs Group CEO David Solomon indicated on Wednesday that the bank's fixed income, currency, and commodities trading (FICC) segment is expected to show a slightly weaker performance in the third quarter, while its equities business remains robust. This outlook triggered a decline in the company's stock price.

Solomon also cautioned investors that, following a strong second-quarter performance, the investment banking division is likely to see a notably quieter third quarter. "Relatively speaking, our equities franchise is still very strong. FICC is a bit softer, but there are still a few weeks left in September," he stated at the Barclays Global Financial Services Conference.

The bank's shares dropped nearly 4%, underperforming other banking stocks that also weakened amid concerns over Federal Reserve interest rate hikes. Goldman Sachs' FICC operations have experienced significant volatility this year, with net revenues surging 32% year-over-year in the second quarter but falling 10% in the first quarter due to market disruptions from geopolitical tensions affecting rate-related activities.
